Indane Gas — got lpg cylinder with less gas

Address:

New Delhi, Delhi, 110049

I am currently living in south delhi. Gas provider is mohanil gas service, hauz khas. I am constantly getting the less quantity of gas everytime. I have filed complaint many times but nobody is taking action. I am attaching a proof this time and it shows 27 kg in total with 15.8 kg cylinder weight. The weight was supposed to be 30 kg (15.8 + 14.2) and i am getting 3 kg less every month.
